TMI3108 from TMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Chip enable pin: drive EN above 1.5V to turn the part on and below 0.3V to turn it off, and do not leave it floating. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | LX | output | Power switch output and switch node connection to the inductor. |
| 4 | VIN | power_in | Power supply input (2.5V to 5.5V recommended range) that must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor. |
| 5 | FB | input | Output voltage feedback pin used to set the regulated output voltage through the external resistor divider. |
